Attempted to replicate Dr. Anton Reiss's 1989 paper on Nova Hart's vocal pitch distribution.

Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.
In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.

If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on?

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.
